The past 40 years have seen automotive Electronic Control Units (ECUs) move from being purely mechanical controlled to being primarily digital controlled. While there has been significant improvements in terms of passenger safety and vehicle efficiency including optimised fuel consumption, rising ECU numbers have resulted in increased vehicle weight, greater demands placed on power,more complex hardware and software, ad-hoc methods for updating software, and subsequent rise in costs for both vehicle manufacturer and consumer. To address these issues, the research presented in this paper proposes virtualisation technologies to be applied within automotive Electrical/Electronic (E/E) architecture. To proposed approach is evaluated through a comprehensive study of the CPU and memory resource requirement in order to support container-based ECU automotive functions. This comprehensive performance evaluation reveals that lightweight container virtualisation has the potential to welcome a paradigm shift in the E/E architecture, promoting consolidation and enhancing the architecture through power, weight and cost savings. Container based virtualisation will also enable a robust mechanism to facilitate online dynamic software updates throughout the lifetime of a vehicle.

The case of a 13-year-old boy presenting with conjunctivitis, urethritis and arthritis (affecting hands and knees) after a Salmonella D infection is discussed.

A two-and-a-half-year-old child presents with spontaneous ecchymosis. In addition to severe thrombocytopoenia, initial investigations show the presence of neutropoenia and signs of immune-mediated haemolysis (positivity of the direct antiglobulin test). This raises the suspicion of Evans syndrome, since this syndrome is characterized, according to the current definition, by the destruction of at least two medullary cell lines in the absence of other diagnoses. Evans syndrome in many cases can be secondary to various pathological conditions. Investigations are carried out in the infectious, immunological, rheumatological and genetic fields, and lead to the identification of a mutation that is one of the causes of common variable immunodeficiency (CVID). So, on that ground, it can be affirmed that the present case of Evans syndrome is secondary to CVID.

Do you want to know what an anti-chiece Latin square is? Or what a non-consecutive toroidal modular Latin square is? We invented a ton of new types of Latin squares, some inspired by existing Sudoku variations. We can't wait to introduce them to you and answer important questions, such as: do they even exist? If so, under what conditions? What are some of their interesting properties? And how do we generate them?

Noise radiated from flow past different configurations of the half-round mirror (HRM) mounted on a plate has been investigated using computational aeroacoustics (CAA). The stress-blended eddy simulation (SBES), together with the Ffowcs Williams–Hawkings (FW–H) acoustic analogy, was employed to predict near-field flow and far-field noise, respectively. The numerical methodology was verified and validated for the standard HRM case against several previously published numerical and experimental data sets, which provides good agreement. Further, (i) the choice of different type of grids for CAA and (ii) the applicability of methods such as the Kirchhoff integral and the FW–H using near field inputs computed from the SBES were assessed. As a next step, the effect of induced noise from the HRM for different (a) aspect ratios (AR) ranging from 1 to 2.5 and (b) inclination of the mirror toward the plate (θ) ranging from 0° to 32° was investigated. For all the investigated cases, the distribution of the radiated noise exhibits a dipole-like structure closer to the plate and a monopole-like structure away from the plate. By inclining the mirror closer to the mounting plate, the emitted noise is reduced both in the vertical and lateral directions of the wake, whereas an increase in the AR of the mirror increases the induced noise considerably. The findings from the current study can provide a deeper understanding for effectively mitigating the induced aerodynamic noise from side-view mirrors.

The range and complexity of technologies that are now being deployed in modern vehicles are increasing at an unprecedented rate. Furthermore, the pace of change is becoming so fast that standardization activities are struggling to support these ongoing developments. The adoption of more robust systems engineering practices and a risk-based approach will therefore be key to meeting the challenges of vehicle development into the 21st century. The emerging need is to ensure the electromagnetic resilience of vehicles, which goes beyond the approaches and boundaries of traditional automotive EMC.

A five-year-old red kangaroo (Macropus rufus) presented with bilateral, firm thickening of the radius, ulna and metatarsal bones with local tissue hyperthermia. Radiographs revealed a soft tissue opacity left intrathoracic mass lying cranial to the heart, and extensive areas of smooth to palisading periosteal reaction along radius, ulna and metatarsus bilaterally. Culture of an aspirate from the mass yielded Actinomyces species. Treatment consisting of injectable penicillin and oral amoxicillin/clavulanic acid, meloxicam and tramadol was implemented for nine months. While receiving antibiotic therapy, the animal’s clinical condition improved, however, clinical signs returned after antibiotics were discontinued. Keeping it on daily medications indefinitely was considered neither practical nor safe for the staff and highly stressful for the animal. The kangaroo was euthanased one year and two months after initial diagnosis. Gross necropsy and histological findings confirmed the clinical diagnosis of pulmonary actinomycotic abscessation with hypertrophic osteopathy.

Effective prediction of the RF impedance properties of two cells in series has been achieved using a hybrid simulation approach based on measured cell properties. This has enabled simple and efficient 3D simulation models to be investigated at a more practical industrial scale, illustrated in this paper using a representative module of an automotive traction battery.
